Richard Bolt

Richard Bolt is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Richard Bolt rather than just read about it. In short: Richard Henry Bolt (April 22, 1911 – January 13, 2002) was an American physics professor at the Massachusetts Institute of Technology (MIT) with an interest in acoustics. He was one of the founders of the company Bolt, Beranek and Newman, which built the ARPANET, a forerunner of the Internet.

Key takeaways

Richard Bolt belongs to physics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Richard Bolt to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Richard Bolt from memory before moving on to harder problems.

Reference excerpt

Richard Henry Bolt (April 22, 1911 – January 13, 2002) was an American physics professor at the Massachusetts Institute of Technology (MIT) with an interest in acoustics. He was one of the founders of the company Bolt, Beranek and Newman, which built the ARPANET, a forerunner of the Internet.

Early life Bolt was born in Peking, China, where his parents were medical missionaries. His family returned to the U.S. in 1916 and settled in California. Bolt graduated from Berkeley High School, California in 1928 and went to college and graduate school at the University of California, Berkeley. Although he initially expected to major in either music or graphical design, he decided on architecture, in which he attained a BA in 1933. At that time, he had already developed an interest in acoustics, combining his interests for music, design and architecture. After his marriage to Katherine Mary Smith, right after his graduation in 1933, they made a honeymoon to Europe, where he became acquainted with a number of scientists from Berlin, and the honeymoon was extended to ten months while Bolt learned German and studied acoustics.

Berkeley Returning to Berkeley in 1934, he entered the graduate physics program, and, earning an M.A. in 1937 and qualifying for Berkeley's Physics Ph.D. program, which he completed in 1939. He performed his research at UCLA, given the fact that Berkeley had no acoustics research facilities at that time. After attaining his PhD in 1939 he worked at MIT for a year on the transmission of sound in various shapes of rooms. Excluding a brief period at the University of Illinois and a stationing in London during WWII, he remained associated with the MIT until his retirement.

MIT and BBN Bolt started a consulting firm with another MIT professor, Leo Beranek, in 1948, and worked on such projects as doing an audio analysis of the JFK assassination, the "18.5 minute gap" in Nixon's White House tapes, and improving the sound in concert halls. In later years, after the addition of one of his former students, Robert Newman, the firm of Bolt, Beranek and Newman, better known as BBN, designed the first modem in 1963, helping computers communicate with each other. This led to work on the ARPANET, which became the Internet. BBN helped develop e-mail and, in 1971, one of BBN's researchers, Ray Tomlinson, chose the "@" sign for e-mail addresses. Bolt retired in 1976.

Worked examples

Example 1 — a first encounter with Richard Bolt

Start with the simplest possible case. Write down what Richard Bolt claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Richard Bolt before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Richard Bolt ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Richard Bolt

In research: Richard Bolt appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Richard Bolt in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Richard Bolt is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1911 births, 2002 deaths, 20th-century American physicists, so understanding it makes those chapters shorter.
In everyday life: Look for Richard Bolt outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Richard Bolt in simple terms?

Why does Richard Bolt matter?

Because it connects several physics ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.
